If the file you attached is the very same one that won't compile for you, perhaps re-installing SigmaStudio, trying it on another computer, etc. might fix the problem. If on the other hand this is "half" your desired project (before expanding to additional channels) -- it's already over 50% MIPS, so a double-sized one would go over. Normally you get a simple "ran out of MIPS" error message for that, but perhaps the compiler hiccuped in this case.

This was under Sigma Studio 3.8 on Windows 7 x64. It had previously failed to compile under Sigma Studio 3.7.7 so I upgraded to see if that was the issue.

If this compiled for Bob, I do have a 32bit virtual machine I can try this on in the morning.

I was able to get the above file to compile by changing the mux from SW Slew to standard. Though this did not help in the full project.

EDIT: 10:00AM Monday Dec 31 2012

I tried both this file, and the complete file in Sigma Studio 3.8 in a virtual Windows XP 32bit machine, and both compiled correctly there.

After a reboot of the Win 7 x64 machine, this file also correctly compiles. So must have just been something that built up and was causing the error after several hours, I'll mark the question as answered until I can reproduce it again.
